Fort Buford State Historic Site preserves remnants of a vital frontier plains military post. Fort Buford was built in 1866 near the confluence of the Missouri and Yellowstone Rivers, and became a major supply depot for military field operations. Original features still existing on the site include a stone powder magazine, the post cemetery site, and a large officers' quarters building which now houses a museum. Fort Buford, located near present-day Williston, was one of a number of military posts established to protect overland and river routes used by immigrants settling the West. While it served an essential role as the sentinel on the northern plains for 19 years, it is probably best remembered as the place where the famous Hunkpapa Sioux leader, Sitting Bull, surrendered in 1881.

The site offers a short film, tours, exhibits, and occasional recreational and educational events.

One of America's earliest religious communities, the Ephrata Cloister was founded in 1732 by German settlers seeking spiritual goals rather than earthly rewards. Gathered in unique European style buildings, the community consisted of celibate Brothers and Sisters, and a married congregation of families. At the zenith of the community in the 1740s and 1750s, about 300 members worked and worshiped at the Cloister.

At the Tipton-Haynes historic site, 11 buildings tell a story of Tennessee's history from early settlement to the Civil War era. Contained within the large white house is the log cabin of Colonel John Tipton. In the 1850s, Haynes changed the front porch to what is seen today and constructed his law office next to the house. The outbuildings include a smokehouse, pigsty, loom house, still house, springhouse, and the large log barn and corncrib from the Tipton period. In addition, there is the home of George Haynes, a slave with the Haynes family. Colonel John Tipton is buried in the site's cemetery.

Belle Grove is an 18th-century grain and livestock farm, which, in its prime (circa 1815), encompassed about 7,500 acres of land. The unique limestone house was completed in 1797 for Major Isaac Hite and his wife Nelly, sister of future President James Madison. The house has remained virtually unchanged through the years, offering visitors an experience of the life and times of the people who lived there in the late 18th and early 19th centuries. During the Civil War, Belle Grove was at the center of the decisive Battle of Belle Grove or Cedar Creek. Today, the plantation includes the main house and gardens, original outbuildings, a classic 1918 barn, an overseer's house, the slave cemetery, a heritage apple orchard, fields and meadows, and scenic mountain views.

Mount Vernon was the beloved home of George and Martha Washington from the time of their marriage in 1759 until General Washington's death in 1799. He worked tirelessly to expand his plantation from 2,000 acres to 8,000 and the mansion house from six rooms to 21. Visitors are invited to tour the Mansion house and more than a dozen outbuildings including the slave quarters, kitchen, stables, and greenhouse. They can stroll four different gardens, hike the Forest Trail, and explore the "George Washington: Pioneer Farmer" site, a four-acre working farm that includes a recreation of Washington's 16-sided treading barn.
